Sometime during Ender's Game my VA-907 was pushed a little too far...now the voice coil rubs and it's as clear as day. I know it's not a HT sub but I'm using it while my regular one is on loan.

I'd like to replace the 8" driver, as I normally use the sub in a small music system. The enclosure is ~1.2 cu. ft and has a 10" passive radiator. Without knowing much else, is there a driver that would get me close?
